UNITED V'STATES rAn'rrrloN AssEMiJNG MACHINE Charles' G. Dauber,Oshkosh, Wis., assigner to The Daubex" Company, Oshkosh, Wis., acorporation of Wisconsin Application June 23, 1939, Serial No. 280,699

s claims. (C1. sia- 31) I am a joint patentee, there is disclosed acomplete machine for cutting, slotting and assembling paper boardpartitions to form carton interior or sub-dividers. In the machine ofsaid patent, due to the fac-t that the paper board material must be bentor extended over and about certain lnstrumentalities, it is notpractical to use corrugated or chip board for the partition formingmaterial as said latter class of material can,

not be bent.

It is, therefore, a primary object of the-present invention to provide apartition assembling machine adapted to g.assemble sets of pre-formedcorrugated or chip board partition strips and which handles thepartition strips or material in such a manner that the same are notsubjected to any bending or damaging deflection.

A further object of the invention is to provide a complete corrugated orchip board partition assembling machine which includes as a portion ofthe entire mechanism, a partition strip assembly feeding arrangement ofthe type covered by my co-pending application, Serial No. 221,902, iiledJuly 29, 1938. f

' A further object of the invention is `to provide a machine of thecharacter described which 35 has adjustable and interchangeable elementsto in the mechanism for steppedly advancing or projecting partitions ofone group into assembly position is synchronized with the mechanism foradvancing the partitions of the other group.

A further object of the inventionis to provide a corrugated or chipboard partition assembling machine which is of very simple construction,is eiiicient, economical and automatic in operation, is strong anddurable, and 'is well adapted for the purposes described.

With the above and other objects in view the invention consists of theimproved partition assembling machine, and its parts and combinations asset forth in the ,claimsl and all equivalents thereof. y

In the accompanying drawings in which the same reference charactersindicate the same parts in all of the views:

Fig. 1 is a front and side perspective View of Ithe improved partitionassembling machine;

Fig. 2 is another perspective view of the machine showing the oppositeside and the rear thereof;

Fig. 3 is a longitudinal vertical sectional view of the machine and on alarger scale;

' Fig. 4 is a fragmentary, detail sectional view taken on line 4 4 ofFig. 3;

Fig. 5 is a detail sectional view taken on line 5--5 of Fig. 4;

Fig. 6 is an enlarged fragmentary plan view of the feeding mechanism forthe longitudinal partition strips; and

Fig. 7 is an enlarged fragmentary side Viewl of a portion of themechanismvshown in Fig. 6.

Referring now more particularly to the drawings it will appear that theimproved partition assembling machine includes a box-like base or casingI0 having mounted therein and thereon many of the working parts of themachine. 'I'he lower portion of the base supports suitable bearingmembers II in which is journaled a main drive shaft I2 of the. machine.Anouter end portion of said shaft has fast thereon a large pulley wheelI3 connected by a belt I4 with the pulley wheel I5 on the shaft of avariable speed electric motor I6. The motor receives its energy from aconventional source of electric current.

Forwardly of the drive shaft I2 and journaled in the casing,transversely thereof, is a clutch shaft Il'. Said clutch shaft is drivenfrom the drive shaft by means of a small pinion I8 fast on the driveshaft which meshes with a large gear I9 carried by a sleeve 23 on onesection of the clutch shaft. A movable clutch element'20 is splined toanother portion of the shaft I 'l and its teeth 2l may be brought intoand out of engagement with the teeth 22 of the sleeve 23. The clutchelement 20 is moved into and out of clutching position by a fork 24mounted fast on a longitudinally extending shaft 25. At the forward endof the machine housing said shaft carries a miter gear 26 engaged byasegment gear 21. The segment gear is on a rod 28 which also carries aclutch lever 29. With reference to Fig. 3 when said clutch lever is inthe full line position the shaft 25, through the various connectionsexplained, will have been turned to have caused the fork 24 to engagethe clutch element 20 with the teeth of the clutch element 23. With theclutch lever in this position, and with the motor `I6 in operation, themechanism for the entire machine will be in operation.' However,l if theclutch lever 29 is moved to the broken line position of Flg. 3, theclutch will be disengaged and the machine will idle. 5 It should benoted that the clutch lever rod 28 is mounted in bracket plates 39carried by 'the lower forward portion of the housing I0. Also, on thedriven portion ofthe clutch shaft I1 there is a friction brake 3i havinga braking I l strip 32 coiled thereabout. The outer end of the brakingstrip is carried by a bolt 33 which is adjustably threaded into-a wallof the housing I9. Adjustments of the bolt 33 will vary the tensionwhich the strip 32 imposes on the surface of the l brake drum 3i. 'Ihebrake is for the purpose of preventing coasting of 'the mechanism. Theinner end of the braking strip is anchored to the housing or frame, asat't (Fig. 3)

On a reduced end of the clutch shaft il (see Figs. 1 and 4) there is aslotted guide block 35 in which is adjustably secured a crank pin 36.Pivotally mounted on one end of the crank pin is a socket member 31which adjustably receives one end portion of/a crank rod 38. Adjustmentsof the crank pin 36 and rod 38 will vary the amount of reciprocatorymovement of said crank rod. The other end of said crank rod is pivotallysecured to the lower end of an arm of a bellcrank lever 39, pivotallymounted on a forward side portion of the housing I0, as -at 40. Anotherarm of the bell-crank lever 39 is pivotally connected with one arm of anupper bell-crank lever 4I by a bar 42, While still another arm of thelower bell-crank lever 39 is pivotally connected with the other arm oithe upper bell-crank lever 4i by a bar 43. This arrangement is effectiveto reciprocate a rack bar 44 whose inner end is carried by the bar 43and whose serrated outer end engages a pinion 45 fast on a forwardtransverse shaft 46. Hence, the shaft 46 is oscillated and the motion ofthis shaft is effective to operate certain longitudinal partitionfeeding mechanism, as will hereinafter appear. Said longitudinalpartitions, indicated by the numerals 41 are pre-formed and areavailable for as sembly with transverse partitions 48 which are fed intoassembly positions by the machine and relative to steppedly advancedsets of the partitions 41.

, With special reference to the heretofore menslotted strips 15. Againstthe side of each strip there is mounted in vertical position a partitionsupporting .panel 49 having an outwardly flared 65 wing 49' on its innerend, as well as a slightly outwardly inclined and tapered plate 50 withan out-turned guiding edge 5I at its upper edge. 'I'he panels 49 areadapted to 'support the rear end portions of forwardly advancedpre-formed partitions 41, while the plates 59 receive and support theforward end portions of succeeding partitions, The succeeding partitionsmay be put into position indiscriminately at any stage of theadvancement of the forward partitions, and the 75 inclination of theplates 50, together with the cut- V turned edges 5l thereof and thewings 49', permit length. Extending vertically upwardly from the topface of each bar is a pair of spaced apart posts 52 with each posthaving the hub portion l0 of a laterally extending finger 53 pivotallymounted thereon. The outer end portion of each of said fingers isreduced and angled for entrance into apertures 54 of the pre-formedpartitions 41, and the fingers are resiliently edged toward the 15 facesof said partitions by springs. The posts and fingers are so arrangedthat when the iingers are in engaging positions, the distance betweenthe ends of a pair is equal to the distance between three apertures 54in a partition. To 20 insure this condition the rear posts 52 may belongitudinally adjustably mounted on their bars. Each slotted strip 15,near its inner end, carries on a suitable bracket a curved band spring55 to engage a portion of a forward partition and to 25 hold it againstthe panel 48, and a resiliently mounted pivotal finger 56 for engaging alower fast portion of a partition.

In order that the bars 88 may be reciprocated, each of the same carriesa depending yoke 83 30 which straddles and is moved by a transverseconnection 84, The transverse connection is moved forwardly andrearwardly relative to the platform 69, lto thereby move the bars 89 intheir slotted strips 15 with resulting intermittent ad- 35vancing'movements of the partitions 41 through -the medium of the uppertransverse rock shaft 46 previously referred to. Said rock shaft hasfast thereon a pair of cranks 86 whose end portions are pivotallyconnected with a suitable portion of 40 the connection 84. Throughthemechanism described theadvancing bars 80 of the partition feedingplatform are intermittently reciprocated forwardly and rearwardly. Onmovements of said bars toward the machine, the ends of the fingers 45 53drop into spaced pairs of apertures 54 in the forward partitions 41.After engagement of the same and continued forward movement of the barsthe engaged partitions are'moved inwardly until the forward limit ofmovement of said bars 5 is reached, the movement being initiallyadjusted so as to bring a series of slots in said pre-formed partitionsbeyond the ends of the panels 49 and into correct assembly position forengagement with a transverse partition 48 being projected 55 downwardlyfrom another portion of the machine. Other specific details of thelongitudinal partition feeding mechanism need not here be referred toand it may be stated that said mechanism is fully described in myco-pending appli- 60 cation, Serial No. 221,902, filed July 29, 1938.

Projecting upwardly from the top forward portion of the housing i 0 is aframe 81 which rigidly v supports an abutment plate 88. Adjacent theinnervface of said plate there is disposed a vertically reciprocableplunger blade 89. The side edges of said bladev carry guide lugs 90which move in vertical slots 9| in the end members of the frame 81,

The mechanism for reciprocating the plunger blade 89 includes thefollowing elements: On one end of the clutch shaftv l1 there is mountedfast a crank 92 to whose outer end a connecting rod 93 is pivotallyattached by' a wrist pin 94. The other end of said connecting rod ispivotally semember reciprocably mounted relative tothe support,resilient means carried by the slide member engageable insuccessive'stripslots upon reciprocations of said slide member in onedirection and automatically releasable from said slots and movablelongitudinally of a strip upon reclprocations o f saidA slide member inthe opposite direction, means for holding a group of forward partitionstrips in parallel, steppedly advanced positions upon movements oftheslide member in the latter direction, means for supporting a stack oftransverse partition strips in inverted positions with the slots thereofopening downwardly, and means for intermittently removing the innermoststrip in said stack downwardly from said stack and engaging its slotswith an advanced series of slots in the rst-mentioned group of strips.
